Grimm Season 3 sees almost every character aware of Nick’s demon-slaying secret. Everyone apart from Sergeant Wu, that is. Actor Reggie Lee has been actively campaigning for his character to join the Scooby gang that’s now been established in the show, and it sounds like his time is finally coming.

We spoke to Bitsie Tulloch, who plays Nick’s girlfriend Juliette Silverton, and she teased what sounds like a fantastic moment on the horizon: “There’s a big, big episode involving Wu coming up, and I can’t give it away because it’s too cool,” she says. “But it’s not what you’d necessarily expect to happen. I guess you could say his reaction will be a lot different from anybody else’s…”

The finale of Season 2 saw Juliette shake off the last of her amnesia, and next year will see her as a fully- ledged member of the Scoobies, lending her scientific knowledge and human perspective to the weekly cases. “Juliette has gone from being a passive character to being completely empowered,” she adds. “It’s fun for me and David [Giuntoli] because we’ve had two seasons of keeping secrets and now we have scenes where our characters aren’t at each other’s throats. They’re asking each other for advice and figuring it out.”

Grimm Season Three airs on Watch on 5 February 2014 at 9pm.
